Application led September 27, 1911. Serial No. 651,550.

or webbing of parallel sided form, with theobject of providing an elastic fabric suitable for use between the parts under tension and in the` gores of corsets, slippers, etc., and wherever such forms of elastic fabric are useful in the artsand manufactures.

In the article of my invention I provide opposite borders or edges of inelastic fabric forming sewing sections by which thefabric is securely connected and anchored in the place where used, and between these sewing sectionsis an elastic part adapted to yield 'under the tension of use.

The fabric lor webbing of my invention is woven as a continuous strip adapted to be cut up into sections or pieces of the required size or length, and in weaving certain parts are reversed.l

In the fabricv of my invention I employ parallel Warp threads., as usual, andthe weft threads are arranged in marginal and intermediate series. The intermediate series weft threads are elastic and the marginal weft threads of usual character. These are laid back and forth in the fabric, preferably with'the returned ends of the several threads interlocked and thus having the same effect as if the weft threadsextended from selvage to selvage, all of which is hereinafter more vparticularly set forth.

In the drawing, Figures 1 and 2 are diagrammatic and plan views representing disf tended forms of my invention, and Fig. 3 is a skeleton plan View. representing only the threads.

In the several figures the same numerals of reference'indicate similar parts.

2 and?) represent the selvage or opposite edges of the fabric or webbing strip.

4t represents the warp threads, 5 and 6 the weft'threads and 7 the elastic strands.

The warp threads i are parallel and in line with the selvage in the several forms of my invention, and are equally .spaced apart. `The weft threads 5 and G come 'within the .selvage edges 2 3 and between said edges and the elastic sections and comprise the in elastic or sewing sections and are advantageously laid in'in the weaving by the employment of two shuttles. These weft threads do not extend into the elastic sec tions as in the Yelastic sections the 'elastic strands 7 constitute the weftv threads and "these elastic strands 7 are laid in in the weaving by a separate, independent and intermediate shuttle.

In Fig. 1 the weft threads 5 and 6 are laid back and forth from the selvage edges toward the center a predetermined distance by the shuttles carrying the sameiand the elastic strand 7 fills in the gap in the width of the fabric or webbing between the weft threads being laid in by the separate, independent and intermediate shuttle, and I have shown and vprefer to interlock the juxtaposed ends of the elastic strand or strands as laid back and forth through the central section and the near returned ends of the weft threads as laid back and forth inthe marginal or sewing sections. This condition is also present in Fig. 2 except that in the parallel sided fabric or webbing shown in Fig. 2, the weft threads taper from a maximum breadth to a minimum breadth, the tapering being preferably 'along each edge of the fabric or webbing,

gradually diminishing from the lower part 'of Fig. 2 to the upper part of Fig. 2 and the elastic strand .7 as laid back and forth and interlocked with the bent ends of the weft threads, as shown in Fig. 2, as `increasing from the lowerend of Fig. 2 to the upper end where the same is shownat its maxiniu width.

Fig. 3 shows the lay of the /weft threads, as indicated in Fig. 2, as if the parts were continued into reverse sections. Iny one section the weft threads increase in width and then extend all across the webbing between the selvage into an inelastic section adapted .to bev severed and then from the maximum decrease to the minimum width before the increase in width starts again, and this condition is repeated progressively through the length of fabric or webbing that may be woven.

In fact, the fabric of myv invention may be woven any length that may be desired and may also be severed into smaller pieces at any desired place, particularly at the maximum and minimum poitions of the weft threads.

I claim asmy4 invention: l 1. An elasticfabric 'o'r webbing compris- Y ing ma'r 'nal inelastic or vsewing sections 1n 'which t e weft threads are lald back and forth for the width of said sections and an intermediate section between' the inelastic and sewin sections which is made elastic and in which the ends ofthe elastic strand,

as laid back and forth through the webbing,-

are interlocked with the ad]acent o r juxtaposed'returned ends of the weft threads.

`2.. An elastic fabric or-webbingcompris -ing marginal inelastic or sewing sections 111 which the weft threads are laid back and \forth.for the width of said sections andan intermediate section between: the inelastic and sewing sections which is ,made elastic and in whlch the ends of the elastic'strand,. as laid back and forth through the webbing, are interlocked with the adjacent or juxta posed returned ends of the weft'threads, and also in which the width of the inelastic sections increase from a minimum to a maximum and then decrease, and in which the width of the elastic sections simultaneouslyy decrease from a maximum to a minimum,

and then increase to the maximum again.

An elastic fabric or webbing comprismg marglnal inelastic or sewing sections in which the weft threads are laid back and` forthfor the width of said sections and an intermediate section between the inelastic.

and also in which at the place of maxlmum width of the inelastic sections, the weft threads extend across the full width of the strip of fabric or webbing between the sel# vage edges, establishing a line of separation. Signed by me this 22nd day of September,
